One of the exterior angles of an isosceles triangle is 115°. find the angles of this triangle

The triangle will have two 65° angles and a 50° angle

If the exterior angle is 115° then the interior angles has to be 65° since that adds up to 180°, a line. Since this is an isosceles triangle, there will be another angle that is 65°. All triangles add up to 180° so add the two angles (65 + 65 = 130) and subtract it from 180°.  

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
